HORSESHOE.

Application led September 20, 1915.

To all 'whom it may concern:

Be it known that I, BENJAMIN F. SPRY, citizen of the United States of America` and resident of Des Moines, Polk county, Iowa, have invented a new and useful Horseshoe, of which the following is a specification.

The object of this invention is to provide an improved construction for horseshoes,

particularly to the end of prolonging the arrangement and combination of elements hereinafter set forth, pointed out in my claim, and illustrated by the accompanying drawing. in which- Figure l is a plan and Fig. 2 a bottom plan of the complete shoe in its original form, one of the heel calks being removed in Fig. 2. Fig. 3 is a rear end view of one side of the shoe. Fig. 4 is a bottom plan of the shoe as provided with certain of the improved devices for renewing the calks, and with my improved heel-plate. Fig. 5 is a front end view and Fig. 6 a side elevation of the same. Fig. 7 is a bottom plan of another form of my improved heel-plate. Fig. 8 is an edge view of the same, partly in section.

This invention relates to and is an improvement on devices illustrated, described and claimed in Letters Patent of the United States granted tome December 6, 1898, No. 615,317, to which patent reference hereby is made.

1n the construction of the device as shown particularly in Figs. 1, 2 and 3, the numeral 10 designates a horseshoe bar or plate preferably formeel and constructed of malleable cast-iron, with a toe-socket 1l and heelsockets 12, 13 cast thereon and integral therewith. The toe-socket 11 has its greatest dimension transversely of the toe portion of the bar or plate 10, which is substantially U-shapein plan, and the front and rear walls of said socket preferably are curved to correspond approximately to the curvature of said bar or plate. A toe-calk 14 is formed of a single block of wood, with the grain arranged vertically, shaped and fitted to the socket 11 and driven and frictionally Y Specification of Letters Patent.

held therein and projecting slightly beyond the lower margins of said socket. The heelcalks 15, 16 are similarly formed and mounted in the sockets 12, 13, and said sockets preferably are'formed with inner walls projecting beyond the margin of the bar or plate 10, leaving apertures 10a therebetween as shown. lVedge-shaped slugs 17 may be driveninto any or all of the wooden calks 14, 15, 16 as desired during icy or sleety weather', and may be removed as soon as the occasion for their use is past, to save unduly marring and injuring the pavement. thas been demonstrated that the wooden calks afford an excellent footing on slippery pavement, but when ice is present in any quantities, it is desirable to use the wedges 17 to roughen the surfaces of the calks. An arcuate slot 18 is formed in and through the inner margin of the toe portion of the bar or plate 10, and a V-shaped slot 19 leads from the central portion of said arcuate slot transversely of and nearly across the said bar or plate. This arrangement of slots makes it possible to bend and adjust the bar or plate 10 and lit it to the foot of the animal on which the shoe is to be used, thus removing one of the greatest objections to the malleable cast-iron shoe as commonly used. This arrangement of slots permits the bar or plate 10 to be bent in either direction somewhat, to either greater or less curvature, and does not impair the eective strength of the shoe.

1n the construction shown in Figs. 4, 5 and 6, a supplementary calk 20 is employed after the wooden calk 14 and its socket have been worn down to such an extent as to ma,- terially reduce the effectiveness of the shoe. rlhe supplementary calk 20 is formed of a piece of thin metal bent or folded to channel form and mounted between the remnants of the front and rear walls of the socket 11, and secured to the bar or plate 10 with screw-bolts or rivets 21, through holes 22 originally formed therein. It is to be understoodthat the supplementary calks 2O may also be used for the rear sockets 12, 13 in a similar manner, if desired. Or a heelplate 23 may be mounted acrossthe entire rear portion of the bar or plate 10. being: suitably secured at its ends to the opposite end portions thereof and bridging the space therebetween, and passing over the apertures 10a, the inner walls of the sockets 12, 13 having by this time been worn entirely away tov said apertnres. The heel-plate 23 n preferably is formed of transversely extending,` laminations, and theV base lamination may be of metal or heavy leather7 While the tread lamination is composed of leather or rubber,V both of which forni excellent tread Y surfaces for certain'conditions, especiallyin summer time.

ln the construction according to Figs. 7 and 8E the tread lamination 23, which may be of leather or rubber, is 'formed with a plurality oic perforations 2li extending entirely through it. A quantity of coal-tar or pitch, indicated by the numeral 255 is poured. between the botto-m layer 23 and the layer next adjacent thereto, and` ills the holes Some of this coal-tar or pitch 25, thro-ugh' the Weight of the animal and through the entrance of small pebbles and other foreign substances, is force/deut of the holes 2l and :Eo ms a coating on the tread surface of the ieel plate7 and this vcoating',together with such quantities of dust and the like as adhere'thereto, not only assists in forming` a reliable tread surface, but also adds mate-y rially to the life of' the ieel-plate by taking the Wear and abrasion therefrom, as the said layer 2321 does not then Contact directly with the ground or pavement.

VThe means shown and described herein for renewing the calks of the shoe adds considerably .to the effective life of theshoeand rconsequently makes it cheaper for the' user;
